Erysimum plant named ‘Balcherlemy’

ABSTRACT

A new and distinct cultivar of  Erysimum  plant named ‘Balcherlemy’, characterized by its medium yellow-colored flowers, dark green-colored foliage, and moderately vigorous, mounded-upright growth habit, is disclosed.

Latin name of genus and species of plant claimed: Erysimum linifolium.

Variety denomination: ‘Balcherlemy’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Erysimum plant botanically known as Erysimum linifolium and hereinafter referred to by the cultivar name ‘Balcherlemy’.

The new cultivar originated in a controlled breeding program in Guadalupe, Calif. during the summer of 2011. The objective of the breeding program was the development of Erysimum cultivars having rich-colored inflorescences and well-branched growth habits.

The new Erysimum cultivar is the result of open-pollination. The female (seed) parent of the new cultivar is Winter Sun ‘Inerywisun’, not patented, characterized by its inflorescences having both creamy yellow and medium yellow-colored flowers, deep green-colored foliage, and moderately vigorous, mounded growth habit. The male (pollen) parent of the new cultivar is unknown. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated open-pollination during April 2012 in a controlled environment in Guadalupe, Calif.

Asexual reproduction of the new cultivar by terminal stem cuttings since April 2012 in Guadalupe, Calif. and Elburn, Ill. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balcherlemy’ as a new and distinct cultivar of Erysimum plant:

-   -   1. Medium yellow-colored flowers;     -   2. Dark green-colored foliage; and     -   3. Moderately vigorous, mounded-upright growth habit.

Plants of the new cultivar differ from plants of the female parent primarily in having a darker mature flower color and a darker leaf color.

Of the many commercially available Erysimum cultivars, the most similar in comparison to the new cultivar is Fragrant Sunshine ‘Walfrasun’ U.S. Plant Pat. No. 13,432. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Walfrasun’ in at least the following characteristics:

-   -   1. Plants of the new cultivar have lighter yellow-colored         flowers than plants of ‘Walfrasun’; and     -   2. Plants of the new cultivar have darker colored foliage than         plants of ‘Walfrasun’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical inflorescence and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balcherlemy’. The plants were grown in one-gallon containers for approximately two months in a greenhouse and one month outdoors in Elburn, Ill. Plants were given one pinch prior to transplant and one pinch two weeks after transplant.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2007 edition, except where general color terms of ordinary significance are used. The color values were determined in June 2014 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe plants produced from cuttings from stock plants and grown under conditions comparable to those used in commercial practice. The plants were grown utilizing a soilless growth medium in one-gallon containers for approximately two months in a greenhouse and one month outdoors in Elburn, Ill. Plants were given one pinch prior to transplant and one pinch two weeks after transplant. Greenhouse temperatures were maintained at approximately 45° F. to 65° F. (7.2° C. to 18.3° C.) during the day and approximately 35° F. to 45° F. (1.7° C. to 7.2° C.) during the night. No supplemental lighting was provided. Measurements and numerical values represent averages of typical plants.
